The Pilgrim. The group then formed a Bible training school and began sending missionaries to locations such as Mexico. In 1922, Rees merged with congregation with the International Holiness Church in order to form the Pilgrim Holiness Church. In 1926, Rees was elected general superintendent, sharing the leadership of the church with two others. In 1930, the church was reorganized, and Rees was called upon to hold undivided leadership.
